DeCaIonTM eliminating scale, preventing corrosion and bio-fouling automatically Cooling water treatment system

DeCaIon™ (DCI) is a revolutionary approach to eliminating scale, preventing corrosion and bio-fouling automatically in cooling water systems. Through applied electro-chemistry and an intelligent controller, DCI removes water hardness from cooling systems without the need for hazardous chemicals. The innovation provides a green technology solution to scaling and corrosion in large building HVAC systems and industrial chiller circuits. The DCI system removes existing scale deposits and prevents further scale formation by driving a non-spontaneous redox reaction which precipitates CaCO₃ and Mg(OH)₂ at the cathode.

The main causes of scaling, Ca²⁺ and Mg²⁺, can then be dumped off the recirculating cooling water. SiO₂ is also removed. The system operates continuously so design heat transfer efficiency is maintained at all times and the requirement for routine shut downs and chemical descaling is no longer required. Water blow-down quantities are also substantially reduced.
